SCOURlNG-ROLL.

SPECIFICATION forming part of Letters Patent No. 462,886, dated November10, 1891.

Application filed March 2'7, 1891- Serial No. 386,619. (No model.)

T0 at whom it may concern:

Be it known that I, Gnonon E. WARREN, a citizen of the United States,and a resident of Exeter, in the county of Rockingham and State of NewHampshire, have invented new and useful Improvements in Scouring-Rolls,of which the following, taken in connection with the accompanyingdrawings, is a specification.

This invention relates to improvements in scouring-rolls particularlydesigned for the purpose of securing or abrading the bottoms of solesand heels on boots and shoes, although it is equally useful for otherscouring or abrading purposes.

The invention is carried out as follows, ref erence being had to theaccompanying drawings, wherein- Figure 1 represents a side elevation ofthe improved scouring-roll, showing the hinged segmental portion swungopen for detaching and attaching the abrading medium. Fig. '2 representsa cross-section on the line X X in Fig. 1, showing the hinged segmentlocked in position when the scouring-roll is in use; and Fig. 3represents a central longitudinal section on the line Y Y in Fig. 2,showing the rollshaft, its pulley and bearings in elevation.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

In the drawings, A represents a bracket or standard, of any desired sizeand shape, having bearings a a, in which the scouring-roll shaft 13 isjournaled, said shaft having attached to it a pulley B, to which arotary motion is conveyed by means of belt-power, as is usual inmachines of this kind.

The improved scouring roll is composed of two parts preferably made ofwood-namely, a main portion C and a segmental smaller por tion (1, whichtogether form a cylindrical roll, as shown in the drawings. The parts 0and O are hinged together at c, as shown in Figs. 1 and i. The part C ispreferably secured to a metal flange D, having a hub or sleeve (Zmounted on the shaft B in any manner suitable for the conditionsrequired.

I) is a shoulder or projection on the shaft B, against which the flangeD is held, as shown in Figs. 1 and 3.

E is an elastic cushion surrounding the roll portions C C, it beingdivided at the meet ing edge 0'', as shown in Fig. 2, said cushion beingpreferably made of felt or similar elastic or compressible material.

F is the abrasive covering, which is preferably composed of a sheet orstrip of said paper, emery-paper, or the like, which incloses thecushion E and is lapped over the meeting edges C of the roll parts (1and C, as shown in Fig. 2.

The improved locking device for securing the roll parts 0 and C togetherand to the shaft B is constructed as follows: It consists of a disk G,adapted to turn upon and also to move longitudinally along the shaft Band to be locked in position on the latter by means of a pin B", securedto the said shaft and projecting through a bayonet-slot g in the hub ofthe locking-disk G, as shown in the drawings. The disk G is normallyforced against the roll 0 C by the influence of aspring H, surroundingthe shaft B between the outer end of the hub of the disk G and a collaror projection B secured to the outer end of the shaft B, as shown inFigs. 1 and 3.

G is an eccentric inclined or cam-shaped slot-hole in the locking-diskG, adapted to receive a pin C on the segment 0 when the said disk isliberated and moved toward the roll 0 O in locking the roll and disktogether.

The operation of the device is as follows: If it is desired to removethe abrasive covering and replace it with another, the disk G is movedaway from the roll and turned sufficiently around the shaft to cause thepin B to enter the lateral portion of the bayonetslot when it will belocked and held in position by the influence of the spring H, as shownin Fig. 1. The segment 0 may now be swung outward, as shown in Fig. 1,to permit the removal of the worn-out abrasive covering and wrapping anew one in its place, after which the segment 0 is closed by swinging itto the position shown in Fig. 2. The disk G is then turned slightly onthe shaft B, so as to cause the pin B to enter the longitudiual portionof the bayonetslot g, causing the disk G to be forced toward the roll 0C and causing the pin 0 011 the segment 0 to enter the slot-hole G, asshown in Fig. 3. By

turning the roll 0 O slightly in the direction of the arrow shown inFig. 2 the roll parts 0 C will be clamped together and to the disk G,which is secured to the shaft, and also causing the turned-in edges ofthe abrasive covering F to be clamped between the adjoining edges of theroll parts 0 C, all as shown in Figs. 2 and 3.

To disengage the rollfrom the locking-disk the roll is turned slightlyin an opposite direction and the locking-disk moved to the positionshown in Fig. 1.

For *narrow rolls a single locking-disk is sufficient, but for longerrolls I may prefer to use two such locking-disks, one at each end of theroll, without departing from the essence of my invention.

Having thus fully described the nature, construction, and operation ofmy invention, I wish to secure by Letters Patent and claim- 1. Thecombination, with ashaft, of a scouring-roll composed of two sections,one of which is hung on the shaft and the other hinged to the former andprovided with alaterally-pro jecting locking-pin, alongitudinally-movable and rotating locking-disk having an ecing-disklongitudinally movable on the shaft, W

having an eccentric groove or slot to receive the locking-pin on thehinged roll-section and provided with a hub havinga bayonet-slot toreceive the projection on the shaft, substantially as described.

In testimony whereof I have signed my nameto this specification, in thepresence of February, A. D. 1891. v
